Khun Au's place is very comfortable and close to public transportation (BTS line). It's very spacious with two bedrooms and two bathrooms. The room is well equipped with a good wifi and beautiful swimming pool.
Au is friendly and the communication went smoothly. If you'd like to stay a bit out of the tourist crowd, this place is quite ideal since you can reach everywhere by skytrain, it's also not far from the boat pier for those who want to visit the old town and travel by boat.
Food wise, there're couple of nice restaurants opposite of the place and 7eleven nearby. The overall stay was very pleasant and I would come back to stay here again if I have a chance.
The not so good point is that it's situatated next to a busy road and it could be noisy (but this applied to most places in BKK if you want to stay a few steps from BTS). The other thing is if you come with a taxi from the airport, it could be tricky to find. Anyway, I'd like to thanks k.Au for being such a helpful host.
